Laser safety statement
The Center for Devices and Radiological Health (CDRH) of the U.S.
Food and Drug Administration has implemented regulations for laser
products manufactured since August 1, 1976. Compliance is
mandatory for products marketed in the United States. This printer is
certified as a “Class 1” laser product under the U.S. Department of
Health and Human Services (DHHS) Radiation Performance
Standard according to the Radiation Control for Health and Safety Act
of 1968. Since radiation emitted inside this printer is completely
confined within protective housings and external covers, the laser
beam cannot escape during any phase of normal user operation.
WARNING!
Using controls, making adjustments, or performing procedures other
than those specified in this manual may result in exposure to hazardous
radiation.

Luokan 1 laserlaite
Klass 1 Laser Apparat
HP LaserJet 3100 laserkirjoitin on käyttäjän kannalta turvallinen
luokan 1 laserlaite. Normaalissa käytössä kirjoittimen suojakotelointi
estää lasersäteen pääsyn laitteen ulkopuolelle.Laitteen
turvallisuusluokka on määritetty standardin EN 60825-1 (1994)
mukaisesti.
Varoitus!
Laitteen käyttäminen muulla kuin käyttöohjeessa mainitulla tavalla
saattaa altistaa käyttäjän turvallisuusluokan 1 ylittävälle
näkymättömälle lasersäteilylle.
Varning!
Om apparaten används på annat sätt än i bruksanvisning
specificerats, kan användaren utsättas för osynlig laserstrålning, som
överskrider gränsen för laserklass 1.
HUOLTO
HP LaserJet 3100 -kirjoittimen sisällä ei ole käyttäjän huollettavissa
olevia kohteita. Laitteen saa avata ja huoltaa ainoastaan sen
huoltamiseen koulutettu henkilö. Tällaiseksi huoltotoimenpiteeksi ei
katsota väriainekasetin vaihtamista, paperiradan puhdistusta tai
muita käyttäjän käsikirjassa lueteltuja, käyttäjän tehtäväksi
tarkoitettuja ylläpitotoimia, jotka voidaan suorittaa ilman
erikoistyökaluja.
Varo!
Mikäli kirjoittimen suojakotelo avataan, olet alttiina näkymättömälle
lasersäteilylle laitteen ollessa toiminnassa. Älä katso säteeseen.
Varning!
Om laserprinterns skyddshölje öppnas då apparaten är i funktion,
utsättas användaren för osynlig laserstrålning. Betrakta ej strålen.

FCC regulations
This equipment has been tested and found to comply with the limits
for a Class B digital device, pursuant to Part 15 of the FCC rules.
These limits are designed to provide reasonable protection against
harmful interference in a residential installation. This equipment
generates, uses, and can radiate radio frequency energy. If is not
installed and used in accordance with the instructions, it may cause
harmful interference to radio communications. However, there is no
guarantee that interference will not occur in a particular installation.
If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the
equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
Reorient or relocate the receiving antenna.
●
Increase separation between equipment and receiver.
●
Connect equipment to an outlet on a circuit different from that to
●
which the receiver is located.
Consult your dealer or an experienced radio/TV technician.
●
Note
Note
Any changes or modifications to the printer that are not expressly
approved by HP could void the user’s authority to operate this
equipment.
Use of a shielded interface cable is required to comply with the Class
B limits of Part 15 of FCC rules.
FCC part 68 requirements
This equipment complies with FCC rules, Part 68. On the back of this
equipment is a label that contains, among other information, the FCC
registration number and ringer equivalence number (REN) for this
equipment. If requested, this information must be provided to the
telephone company.
The REN is used to determine the quantity of devices which may be
connected to the telephone line. Excessive RENs on the telephone
line may result in the devices not ringing in response to an incoming
call. In most, but not all, areas, the sum of the RENs should not
exceed five (5.0). To be certain of the number of devices that may be
connected to the line, as determined by the total RENs, contact the
telephone company to determine the maximum REN for the calling
area.

Regulatory information 25
This equipment uses the following USOC jacks:
RJ11C
An FCC-compliant telephone cord and modular plug is provided with
this equipment. This equipment is designed to be connected to the
telephone network or premises wiring using a compatible modular
jack which is Part 68 compliant.
This equipment cannot be used on telephone company-provided coin
service. Connection to Party Line Service is subject to state tariffs.
If this equipment causes harm to the telephone network, the
telephone company will notify you in advance that temporary
discontinuance of service may be required. If advance notice isn’t
practical, the telephone company will notify the customer as soon as
possible. Also, you will be advised of your right to file a complaint with
the FCC if you believe it is necessary.
